OIL BURNER.

Application filed December 10, 1926. Serial No. 153,964.

This invention relates to a burner suitable for heavy hydrocarbons and the like.

The chief object of this invention 1s to provide burner which will satisfactorily handle and burn heavy hydrocarbon such as crude oil or crankcase oil from which the s diment has been removed either by filtering or decanting.

The chief feature of the invention consists in the arrangement of the burner passages in superposed relation and the overlapping of the burner plates.

The full nature of the invention will b understood from the accompanying drawings and the following description and claims:

Fig. 1 is a top plan view of one form of.

the burner. Fig. 2 is a front elevational view thereof. Fig. 3 is a central sectional view through one of the bur ers.

In the drawings 10 indicates a fuel supply line discharging into a header 11 from which lead the supply lines 12, in turn supplying the nozzles or discharge pipes 13 which e tend into the burners. Each pipe 13 is controlled by a valve 14:.

No special form of nozzle is provided or necessary. The burner consists of a metal housing having the side walls 15 the top 16 and the bot-tom 17, the latter projecting beyond the top and including a trough portion 18. Extending from side to side and in superposed relation are a plurality ofinclined plate partitions 19, the same being arranged in spaced relation and the superposed partitions being successively offset to project over the next lower partition. Each of the pipes 13 discharges into a space or passage formed by the plates, top, bottom irnd side walls in the burner housing. The lowermost passage however, is shown provided wih a fuel supply line 20 controlled by a valve 21. This constitutes an igniting line and the pipe 20 may be connected to a supply for heating the lowermost plate 19. The fuel in the form of oil is discharged from the nozzles 13 and trickles onto th inclined plates 19 and the air enters each passageway at the same end as the nozzle and if the plates are hot, as they always are when operating, the oil drip is vaporized and mixes with the air and is burned before it reaches the .endof the plate. The flame thus passes outwardly from the V passage and upwardly. Each layer of flame heats the next vhighest plate and thussecures vaporization of the oil. The surplus oil not vaporized and burned will drip from the ends of the plates and be collected by the trough 18.

As shown in Fig. 1, there are a pair of burners and they are arranged in diverging relationship. Thcy maybe arranged in converging relationship, that is, reference being had to the direction of the flame discharge. They may be arranged radially which would be the preferable arrangement when a considerable number of burners are employed.

The invention claimed is:

1. A burner of the character described including a tubular casing having an open end from which flames are adapted to dis charge. a plurality of superposed plates in said casing, each extending in substantially the same direction and forming a plurality of superposed passageways therebetwe'en and in the casing, each superposed plate pro jecting beyond the end of the next lower plate at the flame discharge end of the passsageways, a fuel supply for each passageway and discharging therein at'the opposite end thereof, said casing and plates at said opposite and fuel supply end of the passageways being arranged for the air thereto. 7

2. A device defined by claim 1, having each of said plates pitched downwardly from the fuel and air supply end to the flame discharge end.

8.1 1 device as defined by claim 1. having each of said plates pitched downwardly from the fuel supply end to the flame discharge admission of d'and said plates being positioned in parall l relation with each other.

In witness whereof, I have hereunto affixed my signature.
